Confidence Levels

Overview​

EyesOnIt uses confidence levels to tell you how closely your object descriptions match a provided image or video frame. A confidence of 100 for an object description means that EyesOnIt believes the object description closely matches the image. A confidence of 0 means EyesOnIt sees little or no correlation between the object description and the image.

EyesOnIt always asks for at least two descriptions. It provides a confidence level for every object description. It does not provide confidence levels for background descriptions.

Here's an example:

Mail truck

Background Description: rural neighborhood street

Object Descriptioin: mail truck

With the above image and object descriptions, EyesOnIt provides confidence levels of 100 for mail truck. This means that EyesOnIt has very high confidence that the mail truck is present in the image. Typically, confidence levels will not be 0 or 100, but will be somewhere in between.

Prompt Engineering​

Prompt Engineering is the practice of writing good object descriptions (also known as prompts in the Artificial Intelligence world) that accurately and consistently provide a high confidence when a desired condition is present, and low confidence when that same condition is not present. When the difference in the confidence levels between these two cases is large, computer software can reliably use these confidence levels to act on the detection of a desired condition.
